The present work is dedicated to study attacks and countermeasure in MANET. After a short introduction to what MANETs are and network security we present a survey of various attacks in MANETs pertaining to fail routing protocols. We present the different tools used by these attacks and the mechanisms used by the secured routing protocols to counter them. We also study a mechanism of security, named the reputation, proposed for the MANETs and the protocol which implements it as well as its vulnerabilities. Our work ends with a proposal to fend off some of these attacks like Blackhole cooperative, Blackmail, Overflow, Selfish and an implementation of this solution on a compiler of C named Dev.-C++ in order to make comparative tests with the mechanisms already proposed.
